Qi, pronounced “chee”, is loosely translated as energy. It can be used interchangeably with blood when referring to its function in the body, but it also has functions separate from the blood. There is qi in all things just like there are whirring fields of electrons in all matter. Qi, like energy, cannot be created or destroyed, simply transferred.
Acupuncture is the manipulation of qi/blood. In the body, qi nourishes all the organs, muscles, tendons, bones, skin, everything! It brings oxygen and nutrients to tissue and removes waste. It activates the immune system and promotes healing. Qi makes nerves fire and sends signals to the brain to adjust hormones, neurotransmitters, enzymes and other chemicals to balance mental and physical functions.
